SlDEWALK-LIGHT.

SPECIFICATION forming part of Letters Patent No. 625,090, dated May 16, 1899. Application filed January 16,1899. Serial No. 702,322. (No model.)

To all whom it may concern.-

Be it known that I, AUGUSTIN I. DAVIS, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Sidewalk-Lights, of which the following is a specification.

My invention relates to improvements in sidewalk-vault lights in which cement is used for a filling around the lenses; and its object is to prevent the liability of persons slipping by locating non-slippable surfaces in the ocment between the lenses.

As at present constructed all cement-filled sidewalk-lights are slippery, especially when laid on an incline, both on account of the smoothness of the glass and the fact that the cement offers little resistance to the foot in wet or frosty weather. In order to overcome this slippery condition of sidewalk-lights, I have located at the junction between the rows of lenses non-slippable sections made of castiron or other hard metal having pockets in which lead is inserted, which offers a resistance to the feet, and thereby prevents slipping. This arrangement is in the nature of an improvement on the Mason patent, No. 481,702, dated August 30, 1892, in which lead is held in alternately-dovetailed recesses, so as to present a non-slippable surface to the foot.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying myinvention, Figure 1 is a plan view of-a portionof asidewalk-light with the left-hand portion omitting the cement and the right-hand side showing the cement. Fig. 2 is a cross-sectional View on the line 2 2, Fig. 1. Fig. 3 is a sectional View on the line 3 3, Fig. 1. Fig. 4. is an inverted plan View of a section which con tains the non-slippable material. Fig. 5 is a side view of the same.

Like letters of reference refer to like parts throughout the several views.

A represents a section of the base or tile of a sidewalk-light which is provided with openings B, through which the light passes through the lenses C, inserted in said openings. After the lenses are inserted in the openings B the cement B is poured over the entire light and covers the entire surface, which is then rough-troweled to fill the spaces between the lenses. After this step has been taken the sections D are inserted at the junction of the cross-ribs E and F between the rows of lenses.

The section D is composed of four pockets G, all of which are constructed in one piece. On the under side of each pocket G there project downwardly two prongs H and H. The central prongs H on the under side of the pockets G of the section D are forced down into place in the soft cement to fit around the junction E of the ribs E and F, as shown in dotted lines at the left hand of Fig. 1 and also partially shown in section in Fig. 3. These central prongs H have the function of properly centering each section in its place between the rows of lenses. The outside prongs H on the under side of each pocket G serve the purpose of steadying the section in its location. The lower ends of the prongs are curved inward toward each other, so that when cement hardens it forms a lock with the prongs to hold the section firmly in After the sections are inserted the light is- By means of finished in the usual manner. these sections a large area of non-slippable lead is presented without reducing the percentage of light passing through the lenses. The lead is prevented from wear by the edges of the iron pockets, and the durability of the lead is thereby extended, as it is impossible for the lead to wear away any faster than the iron.

This invention is also adapted for use in cement sidewalks where no lenses are used, and the sections may in this case be varied in size and shape to more economical or ornamental forms.

I do not limit myself tothe arrangement and construction shown, as the same may be varied without departing from the spirit of my invention.

Having thus-ascertained the nature of my me invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a sidewalk-light, a base, openings in said base in which lenses are placed, ribs between the rows of lenses, and a section of hard metal containing non-slippable material of soft metal adapted to be placed over the junction of the ribs, and means for centering each section on the junction of said ribs.

2. In a sidewalk-light, a base, openings in said base in which lenses are placed, ribs between the rows of lenses, a section containing non-slippable material adapted to be placed over the j unction of the ribs, and downwardlyextending bent prongs for centering each section on the junction of said ribs.

3. In a sidewalk-light, a base, openings in said base in which lenses are placed, ribs between the rows-of lenses, a section containing non-slippable material adapted to be placed over the junction of the ribs, and downwardlyextending curved prongs for centering each section on the junction of said ribs and for steadying each section in its location.

4. In a cement sidewalk, a section of hard metal containing non-slippable material of soft metal, and means on the under side of said section adapted upon the hardening of the cement to hold the section in place.

5. In a cement sidewalk, a section of hard metal having pockets for holding non-slippable material of soft metal, and means on the under side of said section adapted upon the hardeningof the cement to hold the section in place.

6. In a cement sidewalk, a section of hard metal having pockets for holding non-slippable material of soft metal, and downwardlycurved prongs-on the under side-of said section adapted upon the hardening of the cement to hold the section in place.

7. In a cement sidewalk, a section of hard metal having pockets for holding non-slippable material of softmetal, and downwardlyextending prongs on the under side of said section and curved i-nopposite directions and adapted upon the hardening of the cement to hold the section in place.

8. In a sidewalklight, a base, openings in said base in which lenses are placed, ribs between the rows of lenses, a section of hard metal containing non-slippable material of soft metal and adapted to be placed over the junction of the ribs, downwardly-extending prongs on the under side of each section for centering each section on the junction of said ribs, and downwardly-extending prongs on the under side of each section for steadying each section in its location.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of January, A. D. 1899.

AUGUSTIN I. DAVIS.
